The nondoped thermally activated delayed fluorescence (TADF) devices are increasingly attracting attention due to the superior performances and simple fabrication process. By incorporating two acceptors with phenothiazine, two materials 2-(10H-phenothiazine-10-yl)-10-phenyl-10H-phenothiazine-5,5...

The vibrational characterization of the most stable conformer of 10-isopentyl-10H-phenothiazine-5,5-dioxide (10-I-10H-P-5,5-D) was performed by means of infrared absorption, Raman and surface-enhanced Raman spectroscopy (SERS). Hartree–Fock and density functional theory calculations were carrie...

Both Z and E isomers of 10-(1,2-dibromoprop-1-en-1-yl)-10H-phenothiazine were given by bromine addition to 10-(prop-1-yn-1-yl)-10H-phenothiazine with little stereoselectivity. The crystal structure of the Z isomer showed a usual butterfly structure, while that of the E isomer afforded an anomalo...

The present article describes the synthesis of new fluorinated 10H-phenothiazines by Smiles rearrangement. The reaction of these synthesized phenothiazines with sugar (beta-d-ribofuranose 1-acetate-2,3,5-tribenzoate) afforded the new ribofuranosides and the oxidation of these synthesized phenoth...

We have succeeded in preparation and crystallographical characterization of (E)-10-dihalovinyl-10H-phenothiazine 5,5-dioxides 1–3 (1: X = Cl, 2: X = Br, 3: X = I) and carried out a systematic study of C–X⋯OS halogen bonds. The three compounds were found to have a similar molecular structure an...

A fluoride-induced nucleophilic (phenylthio)difluoromethylation method using TMS–CF2SPh has been achieved. This new methodology efficiently transfers “PhSCF2” group into both enolizable and non-enolizable aldehydes and ketones to give corresponding (phenylthio)difluoromethylated alcohols in g...

The pristine pectin hydrogels and conductive polymer/hydrogel blends were prepared by the solution casting using ferrous chloride (FeCl2) and citric acid as the crosslinking agents, and ibuprofen as the model drug and the doping agent. A conductive polymer, poly(3-methoxydiphenylamine), was succ...

2-Hydroxy-4-amino-4'-methoxydiphenylamine has been prepared and has been found useful for the detection of the end-point in the ascorbinometric titration of hexacyanoferrate(III) ions.

The synthetic versatility of the Buchwald–Hartwig Amination is demonstrated by the synthesis of the industrially important intermediate 2-methyl-4-methoxydiphenylamine. Using four routes differing in the choice of the starting materials, the diarylamine could be synthesized in excellent yields,...

In this study, a novel asymmetric cinnamic acid zinc phthalocyanine (ZnPc, 1) containing three tert-butyl substituents is reported. The asymmetric ZnPc (1) is further linked to amino functionalized magnetic nanoparticles (AMNPs) (1-AMNPs) and to cysteine functionalized silver nanoparticles (cys-...

We have developed two novel dyes based on p-tert-butyl-calix[4]arene in order to evaluate their behavior as sensitizer in photovoltaic devices. These dyes consist in a difunctionalized calix[4]arene with triphenylamine (TPA)-donor, a heteroaromatic π-conjugated spacer, thiophene and benzothiadi...

We report the synthesis and characterization of simple di(aminomethyl)pyridine ligated iron-pincer complexes, which catalyzed the regioselective [2+2+2] cyclotrimerization of terminal aryl and alkyl alkynes to provide the 1,2,4-trisubstituted benzene molecules. Interestingly, internal alkynes al...

A series of novel thiophene derivatives 3–17 were synthesized by initial reactions of 2-amino-4,5,6,7-tetrahydro-N-phenylbenzo[b]thiophene-3-carboxamide 1 and 2-amino-4,5,6,7-tetrahydro-benzo[b]thiophene-3-carbonitrile 7 with different organic reagents. The structures of newly synthesized compo...

A series of new isoprenyl-thiourea and urea derivatives were synthesized by the reaction of alkyl or aryl isothiocyanate or isocyanate and primary amines. The structures of the compounds were established by 1H NMR, 13C NMR, MS, HRMS and elemental analysis. The new compounds were screened for in ...

Optically active new 4-hydroxy-N-(2-hydroxyethyl)butanamides are reported. The structure in the solid state of four racemic mixtures and three enantiomeric pure compounds was determined by X-ray diffraction. The solid state arrangements of enantiomerically pure compounds were compared with those...

Ethylene oxide (EO), an industrial intermediate and gaseous sterilant for medical devices, is carcinogenic to humans, which warrants minimization of exposure in the workplaces. The principal analytical strategy currently used in biomonitoring of exposure to EO consists in the conversion of N-(2-...

Diffusivity of redox shuttle additive in solvent plays an important role in the design of Li-ion battery. As redox shuttle additive, 10-methylphenothiazine (MPT) can give good overcharge protection in LiFePO4-based Li-ion cells, therefore diffusion coefficient of MPT in solvent needs to be known...
